I just put a high flow intake on my 94 accord ex and i had no problems for about a week and now my check engine light is on and the D4 light that tells me what gear im in flashes. I think it might be due to that there is a part that came off my stock intake and i dont know what to do with it now that i have the high flow. Ive been told on this board that it has something to do with my vacume pressure. The car has much lower performance and uses alot more gas now that this has happend. I had the part taped shut and it worked fine and i have also opened it up and the problem is still there. Dont know what to do.
